How to Auto DM on Instagram for Free (Comment → DM Automation)

People keep commenting on your posts, asking for the link. Here's how to send every one of them a DM automatically — for free.

In ReplyAtlas, open Automations and click New Automation. Choose Comments, pick your Instagram account, and give it a name. Add the keyword to listen for — we'll use "free". Keep All posts, so it works on every post and reel. Write the DM. Add {{handle}} to greet each person by name, and paste your link — every click is tracked. On the last step, add a public reply, so others know to check their inbox. Leave everything else as it is and click Create Automation. It's live.

Let's test it. Comment "free" from another account, and seconds later, the DM arrives.

Every person who comments is saved as a lead, so you can follow up later. Start free at replyatlas.com. No coding, and it uses the official Instagram API.
